Need a Downward-Facing Furnace Vent With a More Gradual 90 Degree Bend?
An exposed horizontal PVC furnace vent can leave its opening directly exposed to birds, rodents, insects, leaves and outdoor debris. A compact 90 degree cap may make the required turn, but some installations have enough clearance for a wider long-sweep body.
The LGQF-LL 2 Inch 90 Degree Long Sweep PVC Vent Cap combines a gradual downward turn, an outer-fit connection and a fixed 304 stainless steel screen. It is designed for compatible sidewall furnace intake and exhaust terminations—not as a general-purpose pipe fitting.
- 90 Degree Long Sweep configuration with a wider bend radius
- Downward-facing screened termination outlet
- Outer-fit connection for pipe measuring 2.36–2.375 inches outside diameter
- Compatible with correctly sized 2-inch Schedule 40 PVC pipe
- Integrated 304 stainless steel screen helps deter pests and larger debris
- Condensation drainage path provides an exit for incidental moisture
See the Long-Sweep Structure Before Ordering
The wider curve distinguishes this product from the separate standard 90 Degree model. The long-sweep body requires more space from the wall and nearby pipes. The screened face is the completed termination outlet and must remain open.
Confirm Both Pipe Diameter and Wall Clearance
1. Confirm PVC
Verify that the existing sidewall furnace termination uses compatible PVC pipe—not metal duct or flexible hose.
2. Measure the Outside
Measure straight across the pipe’s outside diameter. The required OD is 2.36–2.375 inches.
3. Check the Space
Confirm that the long-sweep curve clears the wall, nearby pipes, snow level and all required termination clearances.
“2 inch” is the nominal pipe size. This outer-fit product is selected by the actual pipe outside diameter. The 2.36–2.375 inch range does not describe the overall width of the finished cap.
What Each Part Is Designed to Do
90 Degree Long-Sweep Body
The wider bend radius creates a more gradual change of direction than the standard 90 Degree model. This describes the shape—not a guarantee of improved airflow or furnace efficiency.
Downward-Facing Outlet
The outlet faces downward to help reduce direct exposure to rain, snow and wind-driven debris compared with an uncovered horizontal pipe. It cannot exclude every weather condition.
304 Stainless Steel Screen
The fixed mesh helps deter birds, rodents, insects, leaves and larger outdoor debris. It does not turn the vent into a sealed enclosure.
Condensation Drainage Path
The drainage path allows incidental moisture reaching the cap to exit. It is not a replacement for the appliance’s condensate system and cannot guarantee freeze prevention.
Outer-Fit Lower Hub
The lower hub pushes over compatible pipe measuring 2.36–2.375 inches OD. Only this end connects to the existing pipe.
Open Screened Termination
The screened end is the termination outlet and must remain open. Do not attach another pipe, valve or cover to this end.
Know the Safety Boundary Before Installation
A furnace vent is part of an appliance system. The furnace or appliance manufacturer must permit the selected screened termination. This product cannot override the manufacturer’s instructions, airflow limits or required clearances.
- Use only for a compatible sidewall furnace intake or exhaust termination.
- Do not use this model as a vertical rooftop termination.
- Do not use it on drainage, sewer, radon, plumbing, pool or sump-pump systems.
- Do not use it on dryer vents, metal ducts or flexible hoses.
- Do not treat it as a sealed pipe cap, backdraft damper, check valve or backflow device.
- Do not connect another pipe to the screened outlet.
- Confirm allowable screening, airflow, vent length, weather exposure and termination clearances.
- Keep the screen accessible for periodic inspection and maintenance.
What Customers Noticed After Receiving It
Customer comments on this listing focus on the practical details that can be checked by hand: the rigidity of the body, the screen attachment and the fit on a correctly measured pipe.
“Very sturdy item. The screen is well glued.”
“Fit was excellent.”
These comments describe individual installations. They do not replace measuring the pipe, checking available clearance or following the furnace manufacturer’s instructions.

Confidence Comes From Choosing the Correct Curve
A furnace vent termination is a small exterior component connected to an important home system. The goal is not to cover the opening as tightly as possible. It is to select a compatible termination that addresses an exposed opening while respecting airflow, clearance and maintenance requirements.
Careful homeowners and installers measure the pipe, compare the standard and long-sweep shapes and check the available wall space before ordering. LGQF-LL makes those distinctions clear so the purchase starts with the actual installation—not a guess based on a nominal size.

Compare the Other 2 Inch Vent Cap Shapes
The regular 90 Degree model is more compact. This 90 Degree Long Sweep model uses a wider curve and requires more installation clearance. Choose only the configuration permitted by the appliance instructions.

Vent placement, airflow, condensation, frost, snow level and termination clearances must be considered as part of the complete appliance system.
Frequently Asked Questions
What pipe size does this 90 degree long-sweep vent cap fit?
It is designed to push over compatible 2-inch Schedule 40 PVC pipe measuring 2.36–2.375 inches outside diameter. Measure the actual pipe before ordering.
Does this vent cap insert inside the pipe?
No. The lower hub is an outer-fit connection that pushes over the outside of compatible pipe.
What makes this a long-sweep model?
The body uses a wider bend radius to create a more gradual 90 degree change of direction than the standard 90 Degree model. It also requires more installation clearance.
Does the long sweep guarantee better airflow?
No. Long sweep describes the shape. Actual airflow depends on the complete vent system, pipe length, screen condition, furnace design and installation.
Can another PVC pipe be connected to the screened end?
No. Only the lower outer-fit hub connects to the existing pipe. The downward-facing screened end is the termination outlet and must remain open.
Can it be used on both furnace intake and exhaust terminations?
It is designed for compatible sidewall furnace intake and exhaust PVC terminations, but only when the furnace or appliance manufacturer permits this 90 degree screened configuration.
Does the downward-facing outlet completely prevent rain or snow entry?
No. It helps reduce direct exposure compared with an uncovered horizontal opening, but it cannot guarantee exclusion of rain, wind-driven water, frost or snow.
Does the stainless steel screen create zero airflow restriction?
No such guarantee should be made. Any screen can affect a vent system. Confirm allowable screening, airflow limits and inspection requirements in the appliance instructions.
Does the condensation drainage path prevent freezing?
No. It provides an exit path for incidental moisture reaching the cap but cannot guarantee prevention of frost or ice. Weather, condensation, placement and appliance operation all matter.
Can this model be used on a roof, radon, drain, sewer, pool or plumbing vent?
No. This listing is intentionally limited to compatible sidewall furnace intake and exhaust PVC terminations.
Is this a backdraft damper, check valve or backflow device?
No. It is a fixed screened PVC termination vent cap and has no moving valve or damper mechanism.
Should the cap be glued to the pipe?
Follow the furnace or appliance manufacturer’s installation instructions and local requirements. Do not apply adhesive or permanently modify the termination unless the applicable instructions permit it.
Measure the Pipe. Check the Clearance. Then Choose the Long Sweep.
Confirm compatible PVC, measure a 2.36–2.375 inch pipe OD, allow space for the wider curve and verify that a downward-facing 90 Degree Long Sweep termination is permitted.

Important Installation Notice
Always follow the furnace or appliance manufacturer’s installation instructions, local building requirements, allowable vent length, airflow limits, weather-exposure guidance and termination clearances. Inspect the mesh periodically and remove external accumulation only when the appliance is safely shut down and the manufacturer’s maintenance instructions permit access.
